FRANK G. CALDi/VELL, OF XVHEELING, WEST VIRGINIA, ASSIGNOR TO THECALDWELL & PETERSON MANUFACTURING COMPANY, OF SAME PLACE.

SHEET-METAL CEILING-PANEL.

SPECIFICATION forming part of Letters Patent No. 476,185, dated May 31,1892.

Application filed March 1, 1892. Serial No. 423,410. (No model.)

To all whom it may concern.-

Be it known that I, FRANK G. CALDWELL, a citizen of the United States,residing at VVheeling, in the county of Ohio and State of \VestVirginia, have invented new and useful Improvements in Sheet-MetalCeiling-Panels, of which the following is a specification.

This invention relates to that type of metallic ceiling-panels whereinmetallic plates are secured to wooden frames capable of be ing fastenedto the joists or beams and separate or independent sheet-metal moldingsare secured over the wooden frames to conceal the same and provide anornamental appearance.

The objects of my invention are to simplify the prior construction,reduce the cost of manufacture, and provide novel means for attachingthe sheet-metal moldings used over the joints at the edges of thepanels.

The invention consists in the combination of sheet-metal plates, gangsof separated or spaced Wooden blocks arranged along the edges of thepanels and nailed to the joists, and sheet-metal moldings applied overand secured to the separated or spaced blocks.

The invention also consists in a metallic ceiling-panel composed of ametal plate provided along each edge with a gang of separated or spacedwooden blocks, which are nailed to the joists or beams for the purposeof securing the panel in position.

The invention also consists in the combination of sheet-metal platesformed integral with moldings in juxtaposition to their edges to providelateral flanges, gangs of separated or spaced wooden blocks secured tothe lateral flanges and nailed to the joists or beams, and sheet-metalmoldings applied over and secured by nails or similar fastenings to theseparated or spaced wooden blocks.

The invention is illustrated by the accompanying drawings, in which--Figure 1 is a detail sectional view of metallic ceiling-panelsconstructed in accordance with my invention. Fig. 2 is a similar Viewshowing a modification of the invention, and Fig. 3 is a detailperspective View of one of the metallic plates with its attachedseparated or spaced blocks.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, wherein- The numeral 1 indicates a metallic plate, which maybe rectangular or other form suitable for the conditions required. Theplate is provided along each edge with a gang of separated or spacedwooden blocks 2, which are adapted to be secured to the usual joists orbeams through the medium of nails or similar fastening devices 3. Theseparated or spaced blocks are arranged against the outer face of themetallic plate, or that face which is outermost when the ceiling-panelis secured in position. The edges of the metallic plate are preferablyattached to the separated or spaced blocks by nails or similar fasteningdevices 4; but obviously the edges of the plates can be nailed to thejoists or beams and subsequently the separated or spaced blocks securedin position along the edges of the plate by nails, which are driven intothe joists or beams.

When a series of the panels are applied to constitute a ceiling, theadjacent blocks of the panels are covered and concealed bysheet-metalmoldings 5, having parallel flanges 6, which embrace theblocks along the adja cent edges of the plates for the purpose ofconcealing the joints between the panels.

In Figs. 1 and 3 the metallic plate is perfectly fiat throughout itsextent; but obviously it can be fluted or corrugated, as usual in thistype of ceiling-panels.

In Fig. 2 the metallic plate is formed integral with moldings '7 injuxtaposition to their edges to provide lateral flanges, which areattached to the gangs of separated or spaced wooden blocks 2 through themedium of nails or similar fastening devices 4.

By providing the metallic plates with. gangs of separated or spacedwooden blocks along their edges I provide simple means for attaching thepanels to the usual joists or beams and at the same time red uce thecost of manufacture in that small pieces of wood otherwise useless canbe utilized for securing the panels and for attaching the sheet -metalmoldings 5 by nails or similar fastening devices driven through themoldings into the separated or spaced blocks. The separated or spacedWooden blocks also provide for the free circulation of air, which canflow bearranged along the edges of the plates'and nailed to the joists,and sheet-metal moldings applied over and secured to the separated orspaced blocks, substantially as described.

2. A metallic ceiling-panel composed of a metal plate provided alongeach edge with a gang of separated or spaced wooden blocks which arenailed to the joists or beams for the purpose of securing the panel inposition, substantially as described.

3. The combination of sheet-metal plates formed integral with moldingsin juxtaposition to their edges to provide lateral flanges, gangs ofseparated or spaced wooden blocks secured to the lateral flanges andnailed to the joists or beams, and sheet-metal moldings applied over andsecured to the separated or spaced wooden blocks, substantially asdescribed.

In testimony whereof I have hereunto set my hand and affixed my seal inpresence of two subscribing witnesses.
